Of course, the method provided by the embodiment of the present application is not limited to the application scenario shown in fig. 1, but may be used in other possible application scenarios, and the embodiment of the present application is not limited. The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described together in the following method embodiments, which are not described in detail herein. The method according to the embodiment of the present application will be described below with reference to the accompanying drawings.
As shown in fig. 2, a flow chart of a security method according to an embodiment of the present application may be implemented by the security device 10 in fig. 1, and the flow chart of the method is described below.
Step 201: and aiming at any alarm device in any area, acquiring data of at least one environment parameter corresponding to the alarm device in any preset time period.
In practical application, because the wind power on the windward side is larger, the wind power on the leeward side is smaller, the night temperature is lower, the day temperature is higher, and the like, when each alarm device adopts a uniform and unchanged optical fiber vibration threshold value, if the alarm device is arranged on the windward side, false alarms are very easy to generate, and in addition, at the night minimum temperature and the day maximum temperature, the influence on the alarm device is larger, and the false alarms are also very easy to generate.
Therefore, in order to capture and alarm suspicious situations as much as possible, that is, in order to make the vibration threshold of the optical fiber corresponding to each alarm device more fit the actual situation. In the embodiment of the application, the data of the environmental parameters can be acquired by dividing the area to be monitored into a plurality of areas and the time period (dividing each day into a plurality of time periods), and specifically, the data of at least one environmental parameter corresponding to the alarm equipment can be acquired in any preset time period for any alarm equipment in any area. As shown in fig. 3, a schematic diagram of acquiring environmental parameter data provided by the embodiment of the present application is assumed that the boundary of a place to be monitored is divided into 8 areas a-H, 24 hours in a day is divided into 12 time periods, each time period is 2 hours, and 20 alarm devices, namely, alarm devices 1-20, are disposed in the area a. Then, taking the area a, the time period 12:00-14:00 and the alarm device 1 as an example, for the alarm device 1 in the area a, data of at least one environmental parameter corresponding to the alarm device 1, for example, data of environmental parameters such as wind power parameters, temperature parameters and humidity parameters, may be obtained in the preset time period 12:00-14:00.
Step 202: and carrying out structuring treatment on the data of the at least one environmental parameter to obtain structured data corresponding to the at least one environmental parameter.
Because the data of at least one environmental parameter is obtained in a zoning and time-division manner, in order to facilitate the subsequent processing, management, storage and analysis of the environmental parameters, in the embodiment of the application, the data of the environmental parameters can be subjected to structural processing in a zoning, time-division manner and environmental factor type, so that the unordered and unstructured environmental parameters are changed into structured environmental parameters which are clearer, orderly, easy to understand and use.
Step 203: and dynamically adjusting the optical fiber vibration threshold corresponding to the alarm equipment according to the structured data of at least one environmental parameter.
In the embodiment of the application, taking the alarm device 1 as an example, after the structured data of at least one environmental parameter corresponding to the alarm device 1 is obtained, the optical fiber vibration threshold corresponding to the alarm device 1 can be dynamically adjusted according to the structured data of the at least one environmental parameter, so that the optical fiber vibration threshold corresponding to the alarm device 1 is more in line with the actual situation, and the false alarm rate caused by complex environmental factors is reduced.
Step 204: and determining whether the optical fiber vibration value corresponding to the alarm equipment exceeds an optical fiber vibration threshold value.
Step 205: if the optical fiber vibration value corresponding to the alarm equipment is determined to exceed the optical fiber vibration threshold value, performing image capturing through the image capturing equipment corresponding to the alarm equipment, and acquiring a plurality of captured images.
In the embodiment of the present application, taking the alarm device 1 as an example, if it is determined that the optical fiber vibration value corresponding to the alarm device 1 exceeds the optical fiber vibration threshold, that is, there is a suspicious behavior near the optical fiber vibration point, then image capturing is performed on the suspicious behavior through the image capturing device corresponding to the alarm device 1, so as to obtain a plurality of captured images. Wherein the suspicious behavior may be climbing or the like. Of course, if it is determined that the optical fiber vibration value corresponding to the alarm device does not exceed the optical fiber vibration threshold value, image capturing is not performed by the image capturing device corresponding to the alarm device 1.
In a possible implementation manner, when the optical fiber vibration threshold corresponding to the alarm device is dynamically adjusted, in the embodiment of the application, the optical fiber vibration threshold can be dynamically adjusted directly in a matching query manner by presetting the corresponding relation between each environmental parameter range and the optical fiber vibration threshold, so that quick and accurate alarm is ensured.
For example, for the alarm device 1, assuming that the alarm device 1 is disposed on a windward side, and the difference in temperature between day and night is not large, and the humidity is suitable, only the wind power parameter has a large influence on the alarm device 1, then, for the alarm device 1, a correspondence relationship between a "preset wind power range" and a "fiber vibration threshold" may be preset, for example, the preset wind power range 1 corresponds to the fiber vibration threshold 1, the preset wind power range 2 corresponds to the fiber vibration thresholds 2 and … …, and the preset wind power range N corresponds to the fiber vibration threshold N, where N is a positive integer.
Furthermore, when the optical fiber vibration threshold value corresponding to the alarm equipment 1 is dynamically adjusted, whether the current wind power is in the preset wind power range N can be directly determined according to the structural data corresponding to the wind power parameters of the alarm equipment 1; if the current wind power is determined to be within the preset wind power range N, the optical fiber vibration threshold value corresponding to the alarm device 1 can be adjusted to the preset optical fiber vibration threshold value corresponding to the preset wind power range N.
Of course, in the embodiment of the present application, besides dynamically adjusting the "fiber vibration threshold" according to the "preset wind power range", the "fiber vibration threshold" may be dynamically adjusted according to the "preset temperature range" according to the actual situation of each alarm device, the "fiber vibration threshold" may be dynamically adjusted according to the "preset humidity range", and the "preset wind power range" and the "preset temperature range" may be comprehensively considered to dynamically adjust the "fiber vibration threshold", which is not described herein.
In one possible implementation manner, when the optical fiber vibration threshold value corresponding to the alarm device is dynamically adjusted, in the embodiment of the present application, besides dynamically adjusting the optical fiber vibration threshold value corresponding to the alarm device by presetting a correspondence between the environment parameter range and the optical fiber vibration threshold value, the sensitivity of the vibration optical fiber sensor corresponding to the alarm device can be debugged (for example, the debugging is performed in a zoned manner and a time-phased manner) according to the structured data of at least one environment parameter, so as to obtain the debug data of the vibration optical fiber sensor; furthermore, according to the debugging data of the vibrating optical fiber sensor, the optical fiber vibration threshold corresponding to the alarm equipment is dynamically adjusted, so that the influence caused by environmental factors is reduced as much as possible, and the false alarm condition is effectively avoided.
In one possible implementation manner, when capturing images by the image capturing device corresponding to the alarm device and obtaining a plurality of captured images, taking the alarm device 1 as an example, if it is determined that the optical fiber vibration value corresponding to the alarm device 1 exceeds the optical fiber vibration threshold, two image capturing devices closest to the optical fiber vibration point can be determined; furthermore, suspicious behaviors near the fiber vibration points can be subjected to image capturing through the two image capturing devices, so that a plurality of captured images are obtained, and preparation is made for subsequent alarming.
In a possible implementation manner, after image capturing is performed by the image capturing device corresponding to the alarm device, and a plurality of captured images are obtained, in an embodiment of the present application, the captured images may be analyzed to determine whether suspicious behaviors exist in the captured images, and further determine whether an alarm needs to be performed.
Specifically, taking the alarm device 1 as an example, after a plurality of captured images are acquired, whether preset suspicious behaviors exist in the plurality of captured images or not can be determined; if the preset suspicious behaviors exist in the plurality of snapshot images, alarm information can be sent to safety personnel through the alarm equipment 1 so as to inform the safety personnel that safety is threatened.
In one possible implementation manner, after the alarm information is sent through the alarm device, in the embodiment of the application, the occurrence time, the occurrence position and the occurrence type of the preset suspicious behaviors in the snap images can be automatically recorded, so as to help security personnel to know the event situation in time, and further, corresponding and proper measures are taken.
In one possible implementation manner, after capturing images through the image capturing device corresponding to the alarm device and obtaining a plurality of captured images, in the embodiment of the present application, when determining to view the alarm evidence corresponding to at least one alarm device, the alarm evidence corresponding to the alarm devices may be obtained from an independent server; these alert evidence may include, among other things, snap shots and video recordings. Furthermore, when the alarm evidences of a plurality of alarm devices are checked at the same time, the alarm evidences of the alarm devices can be checked without directly connecting each alarm device, and the alarm evidences of the alarm devices can be checked only by acquiring the alarm evidences of the alarm devices from an independent server, so that the occupation of network bandwidth is greatly reduced, the problem of overlong system call evidences is avoided, and the processing reaction capacity of the security monitoring system is improved by shortening the call link of the alarm evidences.
In one possible implementation manner, in order to ensure the security of the evidence and improve the processing capability of the security monitoring system for batch processing of the early warning event, in the embodiment of the application, before the alarm evidence corresponding to the at least one alarm device is called in the independent server, video acquisition can be performed on the preset suspicious behaviors by adopting video acquisition equipment so as to obtain video recordings; further, these video recordings may be stored in a separate server. Therefore, the storage safety of the alarm evidence is guaranteed, and the processing reaction capacity of the security monitoring system is remarkably improved.
In one possible implementation, after the multiple snapshot images are acquired, the multiple snapshot images may also be stored in a separate server in an embodiment of the present application. Therefore, the storage safety of the alarm evidence is ensured, and the processing reaction capacity of the security monitoring system is improved.
In one possible implementation manner, in order to avoid false alarms caused by false acquisition of environmental parameters, in the embodiment of the present application, when environmental parameters of each alarm device are acquired, firstly, for any one alarm device in any area, multiple sets of data of at least one environmental parameter corresponding to any alarm device may be acquired in any preset time period; then, the multiple sets of data of the at least one environmental parameter may be averaged separately to obtain an average data value of the at least one environmental parameter; furthermore, the optical fiber vibration threshold corresponding to any alarm device can be dynamically adjusted according to the average data value of the at least one environmental parameter.
For ease of understanding, the detailed description will be given here with respect to the area a, the time period 12:00-14:00, and the alarm device 1, first, for the alarm device 1 in the area a, multiple sets of data of at least one environmental parameter (wind power parameter, temperature parameter, humidity parameter, etc.) corresponding to the alarm device 1 may be continuously obtained in the time period 12:00-14:00; further, the multiple sets of data of the at least one environmental parameter are averaged respectively, that is, the multiple sets of data of each environmental parameter such as the wind power parameter, the temperature parameter, the humidity parameter and the like are averaged to obtain an average data value of the at least one environmental parameter; finally, the fiber vibration threshold value corresponding to the alarm device 1 can be dynamically adjusted according to the average data value of the at least one environmental parameter. Thus, false alarm conditions due to data errors are largely avoided.
In one possible implementation manner, in order to make the dynamically adjusted optical fiber vibration threshold more practical, in the embodiment of the present application, before the environmental parameter of the dynamically adjusted optical fiber vibration threshold is obtained, an in-field environment investigation may be further performed on the environment, so as to reasonably allocate and install each alarm device, image capturing device, video capturing device, and so on. Specifically, the environment needing to be built and protected is subjected to preliminary investigation by combining field investigation and sensor monitoring. The weather activity information of the environment can be known through field investigation, and the comprehensive grasp of the environmental characteristics and changes is facilitated. By deploying the sensor in the environment, the environmental factors are monitored in real time, data are acquired and analyzed, more accurate and real-time data can be obtained, and the trend and the characteristics of environmental change can be known in depth. The environment is observed and analyzed from different areas and different time periods, and more comprehensive and accurate data support is provided for investigation. And the computer technology is used for carrying out numerical calculation on the environment, so as to explore the rule and influence factors of the environment change in theory and provide scientific basis for further data acquisition resource allocation. Furthermore, the position where the internet of things equipment such as each alarm equipment, the image capturing equipment, the video acquisition equipment, the temperature sensor, the humidity sensor, the wind sensor and the like are specifically installed and the time when the data acquisition is specifically performed on the environment can be reasonably determined.
In practical applications, along the set perimeter, an image capturing device (e.g., a video camera, a still camera, etc.) may be set every 50 meters, and an alarm device (e.g., an alarm horn, a warning light, etc.) may be set every 200-500 meters.
In summary, in the embodiment of the present application, since the optical fiber vibration threshold values corresponding to each alarm device may be dynamically adjusted by collecting the environmental parameters in different areas and in different time periods, the optical fiber vibration threshold values corresponding to each alarm device may be more in line with the actual situation, so as to reduce the false alarm rate caused by complex environmental factors. In addition, because the dynamic adjustment is performed according to the structured data of the environmental parameters, the unordered and unstructured environmental parameters can be clearer, ordered, easy to understand and use, and convenient for subsequent processing, management, storage and analysis of the environmental parameters.
